Application med october 1s, 190s. serial No. 339,222.

citizen of the United States, residingin the citI and countyv of Denverand State of (o orado, have invented certain new and useful Improvementsin Sash-Stops; andI do declare the followin f to-be a full, clear, andexact description o the invention, such as will enable others skilled inthe art to which 1t appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters and figuresofreference marked thereon, which form a part of this specification.

My invention relatesto improvements in stops or holding devices forwindow sash, whereby the sash may be held in any desired position ofadjustment, but at the same time may be easily moved either up or down.

My improved device comprises a spring actuated pin mounted in the frameadapted to protrude therethrough into a groove formed in the sash andnormally engaging a plate which is mounted on said frame, the

bottom"of this groove having a wave-like corrugated suiface, while theengaging extremity of the pin is rounded or curved, thus allowing thesash to be moved u or down as will be readily understood. uring themovement .of the sash it is evident that the pin has a reci rocatingaction due to the engagement of t ie bottom of the groove therewith.

Having briefly outlined my improved construction as well as the functionitis intended to perform, I will proceed to describe the same in detailreference being made to the accompanying drawing in which is illustratedan embodiment thereof.

In this drawing, Figure 1 is a front view of -a window sash and frameequipped with my improvements and shown partl in section. Fig. 2 is afragmentary sectiona view shown on a larger scale. Fig. 3 is a sectiontaken on the line 3-3 Fig. 2. Fig. 4 is a face view of the frame looking`from the inside with the sash removed.

The same reference characters indicate the sanieparts in all the views.

Let the numeral 5 designate the sash as a whole; 6 vthe side railsthereof; and 7 the window frame. In each side'of this frame ,is inserteda casing 8 havin flanges 9 through which screws 10 are passe for t epurpose of securing the casing to the frame. This casing is open toreceive the stop -pin 12 which is surrounded .by a coil spring 13 oneextremity of which en rages a Vshoulder formed in `the casing, w ile theother eit-` tremit acts upon a circular rib or collar 14 forme on thepin near its outer extremity. This pin is normally locked in place inthe case by means of an outer late 15 secured to the flanges 9 of thecasin liy rivets 16. The plate 1'5 is rovided wit i a central openingthrough which the operating extremity l1!A of the stop pin protrudes toengagement with the corrugated surface of a late 17 inserted in a groovel8 formed in tie sash rail 6.

The framemay bere uipped with dustexcludinf strips 19 attached theretoon opposite si es and overlapping the division between the-sash andframe. The corrugated plate 17 is secured to the sash by screws 20 orother suitable fastening devices.

From. the foregoing description the use and operation of my lmproveddevice will be readily understood. Assuming that the device is appliedto the frame and sash as illustrated in the drawing and heretoforedescribed, it is evident that the sash may be raised or lowered at willand that the sto pin 12^ will retain the sash in any desire position ofad 'ustment l-Iaving thus described my invention, what I claim is:

In a 'device of the class described, the combination of acasing adaptedto be inserted in the window frame adjacent the sash, a lpin inserted insaid casingA and provided wit 1 a shoulder, a coil spring surroundingthe pin and acting on the shoulder to force the latter outwardly throu han opening in the casino, and a plate app ied to the casing exterior-lyand having anopening for the outer extremity of the pin, the said platenormally engaging the shoulder of the pin exteriorly, and a corrugatedplate adapted to be attached to the sash and enga e the outer extremitof the stop pin whic is rounded or curve to facilitate the movement ofthe sash, substantially as described.

In testimon whereof I affix my signature in presence o two witnesses.

MILTON M. BAGBY.
